WARNING

Electrical Shock Hazard

Disconnect power before servicing and prevent unit from being switched on

accidentally.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

IMPORTANT

ELECTROSTATIC DISCHARGE (ESD) SENSITIVE

ELECTRONICS

ESD problems are present everywhere. ESD may damage or weaken the electronic

control assembly. The new control assembly may appear to work well after repair is

nished, but failure may occur at a later date due to ESD stress.

• Use an anti-static wrist strap. Connect wrist strap to unpainted metal in the

appliance or water tap

– OR –

Touch your nger repeatedly to unpainted metal in the appliance or water tap.

• Before removing the part from its package, touch the anti-static bag to unpainted

metal in the appliance or water tap.

• Avoid touching electronic parts or terminal contacts; handle electronic control

assembly by edges only.

• When repackaging failed electronic control assembly in anti-static bag, observe

above instructions.

DIAGNOSTIC GUIDE

Before servicing, run diagnostic test rst, then check the following:

• Make sure there is power at the wall outlet.

• Has a household fuse blown or circuit breaker tripped? Time delay fuse?

• Are both hot and cold water faucets open and water supply hoses unobstructed?

• All tests/checks should be made with a VOM or DVM having a sensitivity of

20,000 W per volt DC or greater.

• Check all connections before replacing components. Look for broken or loose

wires, failed terminals, or wires not pressed into connections far enough.

• A potential cause of a control not functioning is corrosion on connections.

Observe connections and check for continuity with an ohmmeter.

• Connectors: Look at top of connector. Check for broken or loose wires. Check for

wires not pressed into connector far enough to engage metal barbs.

• Resistance checks must be made with power cord unplugged from outlet, and

with wiring harness or connectors disconnected.

TROUBLESHOOTING GUIDE

PROBLEM POSSIBLE CAUSE/TEST

LEAKING

• Make sure supply hose connections are not leaking. Check for rubber

gasket damage due to overtightening.

• Make sure end of drain hose is correctly inserted and secured to drain

facility.

• Avoid overloading the washer, which can push the door partially open.

• Check internal hose connections.

• Check the bellows. Remove, reposition, and reinstall the bellows.

Make sure the bellows is not wrinkled.

NO WATER FILL

• Make sure the water supply is turned on fully.

• Normal water level is only 0,5 inches (13 mm to 127 mm) inside the drum

rear side.

• Check for kinks in inlet hoses.

• Check for clogged inlet screens.

• Visually check hot and cold water ow separately at the dispenser with test

programme.

NOISY

• Washer should be leveled properly as outlined in the Installation

Instructions.

• Weak oors can cause vibration and walking of the washer.

• Check for loose lower front bracket.

• Be sure rubber feet are installed on the leveling legs.

• Make sure that the leveling leg lock nuts are tightened.

• High-pitched noise during ll may be due to clogged inlet screens.

• Disconnect the supply hoses and clean the inlet screens.

• Check for proper placement of outer tub support springs.

• Conrm proper damper operation.

TUB IS

COMPLETELY

FULL OF SUDS

• Run the washer through another complete cycle using cold water and no

more detergent.

• Reduce the amount of detergent for thatspecic load size and soil level.

• Loads of towels have a minimal amount of soil present and typically create

more suds.

• Use high efciency or low sudsing detergent specially formulated for front

load washers.

• Check for restricted drain system.

• Check for loose wire connections at control board and pump.

• Check to see if the belt fell off the motor and pulley.

• Perform the Continuity Test.

WET CLOTHES

• Single or tangled items can cause unbalances – add additional towels or

redistribute items in drum.

• Excessive suds may have been present. Check for diagnostic code “Sud”.

• Check connections at all switchesand at the washer control board.

• Check for restricted drain system.

• Perform the Continuity Test.

DOOR WILL NOT

LOCK

• Door is not completely closed.

• Check the electrical connectors and check coils for continuity at the lock

assembly and at the washer control board.

• Check if the door switch is closed. If the door switch is electrically open

when the door is mechanically closed, the door will not lock.

DOOR WILL NOT

UNLOCK

• Unplug and reconnect the power cord. Wait 2 minutes to see if the washer

door unlocks.

• Make sure the door locked switch circuit is closed at the machine control.

• Make sure the belt has not fallen off.

• Check for loose electrical connections at the door lock assembly and at the

washer control board.

• Perform the Continuity Test.

WASHER WILL

NOT START

• Make sure the power cord is plugged into a live electrical outlet.

• Make sure that fuse or circuit breaker are not blown; replace or reset if

necessary.

• Close the door and push the START button to start the washer. The LED

should change from ashing to continuously on.

• The washer may be in a pause or soak period of a cycle. Wait briey for the

washer to start.

• Check for restricted drain system.

WASHER WILL

NOT DRAIN

• Check for restricted drain system.

• Check low and high water levels.

• Check for 230/240V at the drain pump when a spin cycle is selected.

WRONG WATER

TEMPERATURE

• Since this washer uses a low amount of water, the control board regulates

the incoming water ow to temper the actual temperature of the water in the

tub, which may be warmer or cooler than expected.

• Make sure both faucets are turned on fully.

• Make sure the temperature selection is correct.

• Make sure the inlet hoses are connected to the correct faucets and inlet

connections. Flush the water line before lling the washer.

• Check the water heater to be sure it is delivering water at a minimum 49°C

at the tap. Check the water heater capacity and recovery rate.

• If the water heater is located a longdistance from the washer, the water line

may need to be purged prior to starting a wash cycle.

• Check for kinked inlet hoses or clogged inlet screens.

• This washer can sense if the ll hoses are installed incorrectly (reversed

between hot and cold). If the ll hoses were previously installed incorrectly

and then corrected, the washer will need to run through a Hot/Cold cycle.

If the water temperature still seems incorrect, check for proper resistance

on the water valve thermistor.

• Make sure the heating element is functional. Check for condensation on

water temperature sensor connector.

Door Lock failure

If the CUC is not able to lock the Door of the washer after program start or if the

CUC is not able to detect that the door is locked -several re-trials are done-, the

CUC goes to selection mode (LED of Start/Pause button is ashing).

Potential Causes

• Mechanical issue with door / door hook / doorlock interface / hinge / bellow

• Door is not completely closed => Press rmly on the door frame in the area of

the doorlock

For information:

In selection mode, the Start LED is only ashing in case of closed door

contact. If start LED does not ash, the door contact in the door lock is open.

F01

No water detected entering machine or Pressure switch trip / APS level not

detected.

If after ca. 9 minutes the control has not detected that water is entering the machine,

the valves are turned off and the LED Water Tap is switched ON. The appliance

performs a 5 minutes draining to not run in overooding in case the water tap was

open, but the pressure switch / sensor could not detect it and a 2nd lling trial is

performed (when customer presses start again).

The Control is in Pause Mode. Press Start button to restart the program. If water is

lling, the program will run.

Potential Causes

If there is no water in the wash unit:

• Make sure that the water tap is fully turned open.

In case of Hotll make sure that both water taps are fully turned open.

• Check for plugged or kinked inlet hoses or plugged inlet valve lters

• Frozen water in inlet hose leads to this failure

• Check harness connections on valves and CUC

• Verify inlet valve operation

If there is water in the wash unit:

• Check, if Pressure hose is in good condition and properly connected to tub and

pressure switch / APS

• Verify there is not a siphon problem

• Verify wire harness connections to Inlet Valves, Pressure Switch / APS (Analog

Pressure Sensor), and Control Unit (CUC). An open harness connection

between Pressure Switch and CUC cannot be detected. This leads to F01. An

open harness connection between APS and CUC leads to F36.

• Check all hoses for possible leaks

• Verify pressure switch function

• Verify CUC operation

• Verify air trap

If F01 in Test program: wrong Flow meter signal or no Flow meter signal can be the

cause.

• Check wire harness connections to Flow meter and CUC.

• During wash program execution wrong or missing ow meter pulses do not

lead to a failure. During program execution the CUC switches to the time-

controlled lling of the appliances without ow meter.

F02

Aquastop Failure

If the Aquastop contact on the bottom tray of the appliance is closed for more than

10 seconds, an Aquastop Failure will be detected. In an Aquastop condition, the

drain pump will operate 5 minutes. Afterwards the drain pump is off and the door

unlocked.

Potential Causes

If there is water in the bottom tray of the appliance:

• Check all hoses for any leakage

• Check if there was an oversuds due to too much detergent used

• Check the wash unit for any leakage

• Check for traces of dispenser leakage

• Check also for traces of small leakages in the aquastop tray or elsewhere in

the appliance

If there is no water in the Bottom tray

• Check if the Aquastop Switch has a short circuit

• Check if the Aquastop wiring is properly connected

• Verify CUC operation

Long Drain

If the drain time exceeds the drain timeout before reaching the “Level empty”

of Pressure Switch or APS, the LED Pump Filter is turned ON. The timeout is 4

minutes.

The Control is in Pause Mode. Press Start button to continue the program. If water

can be drained out, the program will continue.

Potential Causes

• Check the drain hose and make sure it is not plugged or kinked.

In case of recirculation pump, check also that the recirculation hose is not

plugged or kinked.

• Frozen water in outlet hose or drain pump leads to this failure

• Check the drain pump lter for foreign objects (Filter and Impeller, in case of

recirculation pump: check always both impellers)

• Check the electrical connections at the pump and CUC and make sure the

pump is running.

In case of recirculation pump: check connection of both pumps (also on CUC)

and make sure that both pumps are running.

• Check the electrical resistance of the Drain Pump.

In case of recirculation pump: of both pumps

• Verify CUC operation

• This failure can also be generated by too much foam in wash phase see also

F18 (Foam) description

• Check for Eco-Ball blockage

• In case of APS (Analog Pressure Sensor):

After checking all points above and conrmation that the appliance is draining

well (proper ow rate, not reduced ow): A too high zero-offset of the APS is

also causing this failure. The APS does not reach “ Level empty” anymore.

F04

Too Long Heat Time

If the water temperature is not increasing over 35°C during 50 minutes of the rst

heating step in the program, the program is nished without further heating.

This failure is handled as delayed failure. Only at the 10th occurance the customer

is notied.

Reprogram CUC in case of F04 to clear the failure counter otherwise the failure will

remain.

Potential Causes

• Check the electrical resistance of the Heater

• Check Wire Harness connections to the Heater, NTC, and Control Unit (CUC)

• Check the electrical resistance of the NTC (failure can also occure, when NTC

resistance is not changing with temperature)

• Check CUC operation

F05

Water Temperature Sensor Error

If the water temperature sensor (NTC) value is out of range, the program runs

without heating. If the NTC value is in range, but there is not at least a change in

NTC value of +2°C during heating or -2°C in case of re-lls during heating detected,

the program continues without additional heating.

Potential Causes

• Check the NTC resistance

• Check connections to the NTC and CUC

This failure is handled as delayed failure. Only at the 10th occurance the customer

is notied.

During the time until the failure is declared there might be calls like: “poor wash

performance / does not heat”.

Reprogram CUC in case of F05 otherwise the failure will remain.

F06

Blocked drum / Overload of motor

The control unit is not able to move the motor or it is very hard to move the motor.

There are 10 re-trials to run the motor. If the blockage is not too strong, the program

continues and nishes with reduced motor movement. If the blockage is strong, the

cycle is stopped with failure indication.

Potential Causes

• Check wire harness and connections between the Motor and CUC

• Check drum for blockage (make the check slowly and only for short time, the

drum will be braked, if you rotate the drum for several seconds and / or if you

do it fast)

• Instruct customer for trapped laundry

• Check resistances of the Motor windings

• Check if the correct motor is mounted

• In case of Direct Drive Motor: Check if the correct combination of stator and

rotor is mounted.

F07

Motor Control internal Failure

The CUC may have detected a hardware damage.

Potential Causes

• Check CUC by running Test Program: if failure occurs exchange CUC

• Motor or Motor Control over-temperature detection can be also included in

F07. In this case it is not displayed to the customer. Anyhow see points from

F10.

• Check wire harness and connections between Motor and CUC

• Check if the correct motor is mounted

• In case of Direct Drive Motor: Check if the correct combination of stator and

rotor is mounted.

F08

Incorrect Heating

The main control has detected a heater circuit failure. These failure modes are

checked before the program starts and at the end of the program. The program is

running without heating.

Potential Causes

• Check the resistance of the heater connectors (L and N) to PE

• Check the resistance of the heater (L to N)

• Check the connectors to the heater and CUC and check wires

• Check the CUC

This failure is handled as delayed failure. Only at the 10th occurance the customer

is notied.

During the time until the failure is declared there might be calls like: “poor wash

performance / does not heating”.

Reprogram CUC in case of F08 otherwise the failure will remain.

F10

Drum Overload (over-temperature)

The CUC has detected a too high temperature. The detection until failure

declaration can take long time depending on the degree of overload.

Potential Causes

• This failure is normally not visible in the Test program or at a short time of

motor running, because it is an effect of long running motor under heavy load

• Check for missing motor movements

• Check for drum blockage (make the check slowly and only for short time, the

drum will be braked, if you rotate the drum for several seconds and / or if you

do it fast).

• Also laundry can block the drum.

• Check for noise or friction during the drum rotation.

• Check if the machine was overloaded.

• Check for several consecutive and/or long programs.

• Check the ambient temperature -> instruct the customer.

• Check built in conditions before service visit -> instruct the customer.

If the failure is permanent

• Check motor for defect (see F06)

• Check if CUC is defect

(Eventually Icon

Door open is ON)

F13

CUC Failure on Doorlock control circuit

If CUC detects a defect of the doorlock triac or doorlock relay, F13 is displayed This

check is done at start of program and at the end of the program.

Potential Causes

• Check the wiring / harness between the CUC and the Door Lock

• Check if the door contact of the doorlock is closed in case of closed door

• Check if doorlock can lock and unlock

• Check points for F29 / FdL

• CUC defect

Only during

service Test

Only during

F15

Drum Up Circuit Missing ( only for TOPLOADERS with DRUM UP Circuit )

If the CUC is not detecting the Drum Up switch closing during Motor rotation this

failure is displayed. This failure is ONLY detected during the Service Program

Potential Causes

• Check the position of the electromagnetic device

• Check the position of the reed sensor

• Check the resistance of the reed sensor

• Check the wiring connection between the reed sensor and the CUC

F20

Control Board Failure (or eventually Heater failure)

The control unit has detected, that the main or the heater relay has short or open

circuit or that the heater has an open circuit or reduced insulation resistance to PE.

Potential Causes

• First check, if the heater is ok

• Check the resistance of the heater connectors (L and N) to PE

• Check the resistance of the heater (L to N)

• If heater has reduced resistance of L or N to PE => replace heater and run test

program (should be no failure of CUC in this case)

• If heater has open circuit: Replace heater and CUC (relay failure on CUC)

• Check the connectors on the heater and CUC and check wires If heater and

wires are ok:

• CUC is defect (relay failure on CUC).

F21

User Interface Communication Error

If the communication between user interface module and CUC is disturbed this Error

is displayed.

Potential Causes

• Check wiring connection to the User Interface.

• Check User Interface

• Check Control Unit

F24

OverFlow Failure

If the Overow contact on the pressure switch is closed or the Control Unit has

read the overow level in case of APS, the drain pump is switched on for 60". The

wash program continues. The overow failure condition is reached, if the overow

contact or signal is detected the 5th time in the same wash program. In an Overow

condition, the Door will remain locked, and the Drain pump runs in intervall mode.

Potential Causes

• Check with customer, if program with high water level (e.g. delicate) was used

with too big load => instruct customer for small max. Loads for such cylces

• Check the drain hose and make sure it is not plugged or kinked

• Check Wire Harness connections to the Drain Pump, Pressure Switch/APS,

and Control Unit

• Check the Inlet Valve for proper shut off

• Check / Clean Drain Pump Filter from foreign objects

• Check for Drain Pump Failure

• Check the Pressure switch / APS for proper operation

F26

Pump Driver Failure

If the CUC detects during the wash program that the triac of the pump is defective, it

will display this failure.

Potential Causes

• Run Test program to check the CUC. If the failure occurs replace the CUC

• Check drain pump

• Check drain pump resistance (too low resistance and therefore over current of

drain pump can damage the pump driver)

F27

Motor phase loss

The CUC detected an open circuit in one of the motor phases or in the harness

connection to the motor. The motor cannot turn anymore in this case.

Potential Causes

• Check the harness to the motor

• Check the motor

• Check the CUC

Only during

service Test

F29

FdL

Doorlock cannot unlock, mechanical issue of doorlock blockage, …

(in test program: also Doorlock cannot lock)

Potential Causes

• Check for a mechanical problem on the Door Lock system (also Door, Hinge,

Bellow and Door hook)

• Check the wiring / harness between the CUC and the Door Lock

• Check if bellow is properly mounted (if doorlock was getting wet due to wrong

mounted bellow, exchange doorlock)

• Press rmly on door frame in area of doorlock, try to lock/unlock doorlock

• Start test program. If the problem persists Error Code F29 or FdL will be

displayed

• Emergency unlocking, if CUC is not able to unlock doorlock:

Doorlock can be unlocked by pulling the emergency release strap behind

the plinth or by pushing from top (with removed table top) on the exible part

on top of the doorlock. Always drain the water before using the emergency

release (by drain program or manually by opening the pump lter – wait until

water has cooled down).

• If door can also not be opened by emergency unlocking: disassemble electrical

box from doorlock support with small screw driver (it is snapped to the doorlock

support), when partly disassembled try emergency unlocking again

NOTE to locked door:

In case of missing mains supply or in case of certain failures of electrical

components, the door has to be kept locked. E.g. if water level and/or water

temperature cannot be assured to be safe for the customer. This is a request

coming from the approval standard.

In this case it is not F29. In this case the locked door is not the origin of the problem,

but the required reaction. Use the emergency unlocking in cases where it is not

possible to unlock with the CUC.
